Adding to the excitement is Pharrell Williams, Roberto Cavalli, Dolce & Gabbana, Marni, Shourouk, Missoni, and more, who have all put their own creative spin on the official “Brazuca” 2014 Adidas World Cup soccer ball. The creations range from simple like Williams’s (above right) to ornate like Cavalli’s (below right). Rendering each ball a unique work of art, the designer’s masterpieces will be auctioned off on eBay beginning now until the World Cup Finals. All proceeds from the sales will be donated to the Gol de Letra Foundation, whose mission is to improve living conditions for children in the Brazilian favelas through art, culture, education, and sports.
